i'm using newton with irrlicht... how can i integrate a cloth sim in there?

What do you mean ???
Something like a jacket (coat) or tousers ????
This has nothing to do with Newton, or physics at all, I think...
But you should really search for a Newton forum for questions related to Newton !!!

i think he mean that the clothes move physically correct

Hmmm, I see...
Well, you could create the clothes with bones for the animations and let them act like a ragdoll or joint-chains...
But this is not possible with the standard Irrlicht sdk...
Irrlicht doesn't support direct manipulating of bones, for this you have to add my CustomBones extension to Irrlicht !!!
This should work with any physics engine...

is it possible by using irrlicht and newton to attach a system to the object, consisting of a matrix of points that are tied by some kind of springs and that can move according to the forces applied to them?

Yes it is.

Yes, it is !!!
It's similar to what I meant in my 2nd reply...

Hmm. I got an error message after posting and a refresh didn't show my post at first so I posted again. Strange.

can anyone give me a reference point on how can i do this in newton?

Newton does not support cloths, but as Acki said you can manipulate with irrlicht joints and newton bodies and joints for creating of similar thing. I have plan to do some tests but for good cloth simulation you will need many sprites, so I suppose that this will be heavy for CPU.
For reference point look for dhelton9000 posts in newton forum or here. He made some interested experiments. Also Acki made interested demo for using of Irrlicht bones with Newton, even with Ragdoll.

i'm actually planning to make a cloth simulation system like the one in 3d studio max 8... and i have a 450 mhz cpu and it work's perfectly on my pc

Most cloth simulations are nowadays performed by vertex shaders which could be the reason it's not that much CPU intensive! But you could use that way, too. Would be even simpler to integrate with Irrlicht meshes.

See sample source for cloth sim included with the Apocalyx engine:
http://apocalyx.sourceforge.net/
Ready made demo app also included. Really cool, check it out.
